Looks to be made by Processed Plastic in Aurora Il.It may just have the location under the decal shown on the floorpan in your pic. Directly under the decal it may or may not say Processed Plastics....I have seen them both ways.I have a 67 SS Camaro in a mustard yellow w/factory hub caps....and....a 67 Camaro with a stinger hood,rear spoiler and torque-thrusts...Looks like a neat drive-shaft promo car made from this mfg..COOL !
